I degoogled my phone last weekend and installed /e/OS. I had to use command line install, but it was very easy and worked like a breeze.
All the apps that used before degoogling are available and work great, and everything feels very smooth.
I did swap the standard launcher for the Fossify launcher, and I had to use adb to remove a couple of built-in apps with alternatives, but this is down to personal preference (though I wish it was possible to uninstall without adb).
Overall I am really happy so far.
